comment Surprise exam paradox?
I don't quite understand why the knowledge gets represented as a partition of the states of the world. Isn't it possible that in one situation we know the world is in state A or B and in another we know it is in A or C?

comment A challenge by R. P. Feynman: give counter-intuitive theorems that can be translated into everyday language
If the question is written as, "We search until we find a parent who has two children with one a boy born on a Tuesday and the other is not a boy born on a Tuesday", then it's much more obvious what is going on
